Important Precautions

Please observe the following critical precautions before and during installation to ensure the longevity and proper function of your new screen:

• Fragile Product: The screen is made of glass and is very fragile. Handle with extreme care.
• Pre-Installation Testing: Always test the screen thoroughly before proceeding with full installation. Do not remove any protective films or labels until testing is complete and successful.
• Static Electricity: Be mindful of static electricity. Static discharge can damage electronic components. Consider using anti-static precautions.
• Cable Bending: Do not bend the LCD cable excessively. Curvatures greater than 90 degrees can lead to a black screen or display issues.
• Professional Installation Recommended: If you are not experienced in phone repair or lack professional maintenance skills, it is strongly recommended to seek assistance from a qualified repair shop. Self-installation without proper knowledge can lead to damage and void the product's functionality.

Pre-Installation Testing

Before fully installing the screen, it is crucial to test its functionality. This step helps identify any potential issues before permanent attachment.

1. Connect Flex Cables: Carefully connect the new screen's flex cables to the corresponding connectors on your phone's motherboard. Ensure they are seated correctly and securely.
2. Power On: Power on your device. Check for display functionality, touch responsiveness across the entire screen, and proper color reproduction.
3. Check for Defects: Look for any dead pixels, lines, flickering, or abnormal display behavior.
4. Test Touch Sensitivity: Navigate through menus, open apps, and perform gestures to confirm the touch screen is fully responsive and accurate.
5. Proceed or Contact Support: If the screen functions correctly, you may proceed with the full installation. If any issues are observed, disconnect the screen and contact customer support before attempting further steps. Do not remove protective films or adhesive until the screen is confirmed to be working.

• Disassembly: Carefully disassemble your phone, removing the old damaged screen. Pay attention to all screws, connectors, and adhesive points.
• Clean Frame: Thoroughly clean the phone's frame, removing any old adhesive residue or glass fragments. A clean surface is essential for proper adhesion of the new screen.

Troubleshooting

If you encounter issues after installation, consider the following common problems and solutions:

• Black Screen: If your phone displays a black screen after installation, press and hold the power key and volume down key simultaneously for about 10-15 seconds. If the phone vibrates, it often indicates that the main flex cable is not properly installed. Re-check all cable connections.
• Incorrect Screen Response / Unresponsive Touch: This can be due to a loose flex cable connection or static issues. Ensure all cables are securely seated and consider re-testing after a full power cycle.
• Display Issues (Pixel Distortion, Lines, Wrong Colors): These often point to a damaged flex cable or a faulty screen. Ensure the cable was not bent excessively during installation. If the issue persists after re-checking connections, the screen may be defective.

For persistent issues, it is advisable to consult a professional repair technician.
